STAPLING MACHINE.

SPECIFICATION forming art' oi Letters Patent '1\ To. 532,138, dated January 8, 1895. Application filed Jul 11,1894. Serial No. 517,209. (No model.)

.T0 all whom it may concerm Be it known that I, WILLIAM J. BROWN, a citizen of the United States, and a resident of the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Machines for Inserting and Clinching Metallic Staples, of which the following is a full, clear, and exact description, reference being had to the accompauying drawings, forming a part of this specification.

My invention relates to machines for inserting and clinching metallic staples in which a series of said staples is mounted in train upon a mandrel or bar contained within the magazine of the machine, the latter being provided With a driver blade to open and close the throat channel of the magazine and A drive the staples ejected therefrom into such throat; the magazine being provided with mechanism to automatically feed the staples forward to the driving mechanism when and as required.

. My present improvements relate to mechanisms for actuating the staple feeding and driving member, to adapt such machines to be operated by foot power; and consist of the combination with the frame or body of the machine upon which the staple feeding and driving member is mounted, of a vibrating centrally pivoted lever arm connected at one end to a link arm actuated by a cam upon the end of aswinging treadle bar; also of the combination with such swinging treadle bar and a pivoted clinoher actuating arm, of means between the same to actuate said clincher arm alternately with the staple drivingmechanism.

In the accompanying drawings illustrating my invention, Figure 1, is a side elevation, partly in section and partly in dotted lines, of the complete machine showing the several parts in their normal position. Fig. 2, is a side elevation of the machine with the lower end of the treadle broken Off showing the position of the parts on the first partial movement of the treadle. Fig. 3,is a like view showing the second position of the parts on a further and continued swing of the treadle. Fig. 4, is also a like view of the machine showing the position of the parts On the completion of the backward swing of the treadle. Fig. 5, is averticallateral section on the line 1 -2 of Fig. 1, showing'the construction of the clinching mechanism. v

The supporting table is represented at A,

tended arm B curving upwardand. inward, v

and an upward projecting end B substantially'of the form shown and provided at its top with an iutegrally constructed saddleback plate mounted upon and formed integrally With a pillar N which is hollow for the purpose hereinat'ter described. The staple feeding and driving, member C With its driverM need not be described; reference being hereby made to my pending applicati0nSerial No. 497,987, for the preferred form of such member. This member is pivotally mounted at f upon the arm B. Of the frame. A lever arm F' is secured at its forward end m' to the driver blade M as described in my aforesaid application, and this lever arm is oentrally pivoted upon a link F which has its lower end pivotally mounted at fin the arm B of the frame.

Thelower end of the 'vibrating ,lever arm F' is pivotally connected at h to a link arm F which is provided at its lower end with a cam roller h'.

The base portion B' of the frame of the machine has a lng?" extending downward, and upon the Same is pivotally mounted at t, a treadle D provided With a foot pieee CZ' at its lower end, and it-s upper free end With a cam link E coustructed and shaped as shown in the several figures, namely, with two courses or Openings c and 6 substantially at right angles to and opening into each other. This cam treadle is so shaped and weighted that by gravity it will assume the position shown in Fig. 1, viz., with the foot piece about on a Vertical line With the elinching plate'of the machine, and with the cam roller h' of the driving link F normally in the course Or opening 6 Of the cam link. Upon the journal t which supports the treadle upon the lug 7' is mounted to swing loosely an eye link K to which is adjustably secured by jam nuts the screw threaded end of a rod H the other end of which' is pivotally secured at, hv tothe; link F. This is to adj'ustably regulate the; throw of the said link F in the cam E; and at the top of the treadle D are provided two lugs 70, k, between which the end of the pivoted elincher arm R depends, s0 that by vibration of the treadle Said lugs k, k, Will contact. with and thus move the clincher arm R which is mounted pivotally at S against the side face of the base plate B' of the machine.

In Fig. 1 is shown a saddle-back plate N. The flat plate N' shown in dotted lines in Fig. 1, may be placed upon this saddle-back plate as it is provided with parallel conical ribs n, n, on its under face to adapt it to rest upon the angular Sides of the, sad'dl erback plate. The pillar N (seeFigz). i's: made hollow so: as to admit the free passage of' abar 'n' which when vertigcally reciprocated strikes the swinging clinch-ingfi ngers n as: shownin- Fig. 5.

The operation of the. machine is: as fol lowsz-The normal position of" the parts be ing' as shown-- in Fig.1^, with the driving mem ber held up from the clincher plate by the n weight of the treadle, papers are placed upon the saddle-back or on the flat cl incherplate, as the case maybe, and the. foot beingplaced upon the treadle at d" a slightmovement backward thereof will bring the lower faceiot the staple feedi-ng and driving member down upon the top surface of the papers as: shown in Fig. 2, and a further and continu ous back movement of the tread l e will bring the driver blade down upon the crown: of, the; staple and drive it through the papers. The cam roller h" will then be upon the point 6-' between the two cam slots e, 6 as shown in Fig. 3, and the further and continuous: and final backward movement of the treadle Will then cause the openoam slot; ato pass upward for its full length on the roller lt which thus maintains the end* of: the driver blade fixedl y against the crown of thed riven staple whileit is being elinched. The-lng 7G will then contact with the lower end of' the pivoted clincher arm R, driving its other endupward against the rod n' in the pillar N and thus the clinching fi n-gers n will be actustaples are. eiected and driven singly and in s-nccession on: the reciprocation of a contained driver, the combination with a supporting frame upon which the feeding and driving member is pivotally mounted, of a 1 centrally pivo-ted rocking lever secured at One end' to the driver blade, a weighted treadle bar pivotally mounted and provided at itsfree x upper-end with a slotted cam link E, and a connecting link F provided at One end with cam roller h' and pivotally secured at its other end tosaid rocling levenwhereby on the reciprocal swing of the treadle the driver blade will be reciprocated* verti-cally and in unison with ithe described movement of the treadle; substantially as and for the p-irrposedescribedn 2. The combination in a machine for drivi ngan d clinohi-n-g;stapleshavingafeeding and d rivi n gr member from which the sta-ples are ej ected' and dri vensingly and in success-ion on the: reciprocationof a contained driver, of a supporti ngframe: B B B therefor, rocking l-e ver F' adapted to actuatethe driver blade, al'ink-F by which said lever is mounted u ponthes irpporting frame, arwei ghted treadle bar D pivotal ly mean-ted: and provided at its i upper-free end with a slo-tted cam link E, a gconnectin g actuati n g arnr F provided with l i cam roll'er hflq and adjusting devices to l imit thes wi'ng of the aetuati ng' arm F consisting of' the rod H between said arm F and the Sha-ft upon which the-treadi'e is mounted; sub stantiall y as described.
